cracked one of the motor-mounted capacitors
sure the capacitor is not the cause of the problem
i would replace the cap!
you can never be sure.if you cracked it, then replace it!
Then today after an incredibly light nudge into a wall indoors at a height of about 6 inches (barely enough to fold the rotors back), the DF can't keep it's sh*t together.
also i would have a look at the gyros and also the TI sensors! .. are they alined and paralelle to the main board!?
